Dear All,
I want to calculate a structure with perfect AFM configuration.
When I add spin-orbit coupling, I think, the band-structure should be double 
degenerate anywhere because of its perfect AFM configuration. But my 
calculation band-structure split at some place. Its total magnetic moment is 
not perfect zero but 0.01.
So, do you have some motheds to force the results to perfect AFM configuration? 
I read the UG and find AFM calculations, but runafm_lapw does not work with 
spin-orbit coupling.
Thank you very much!
